[LAU] midi clock

[becks]

Hi all,
i have one midi device that send midi clock info.
this clock is used to set arpeggios and LFO time, and maybe other stuff.
this device don't have lcd screen, so i can see exactly current bpm.

1) how compute (easily) bpm over midi channel? (with aseqdump i can
see clock message repeated over and over)
2) how to send standard midi message to set new bpm?

thanks!
